At 2'0 clock, the hands of a clock make an acute angle and a reflex angle. How much is the reflex angle (in degrees)?
Angle between the hour hand and minute hand = (30 H - 11 M /2) H = hour, M = minute At 2, 'o clock H = 2 M = 0 So, (30 x 2 - 11 x 0 / 2) 60 - 0 = 600 Now, Reflex angle = 3600 - 600 =3000
375% of 320 - 80% of 40 ÷ √256 = ?
√? = 80% of 720 - 22% of 2500
9999² + 1111² =?
What is the value of 143 + 163 + 183 + … + 303?
45% of 360 - 160 + ? = √324
Find the value of {(3125) (n/5) × 5 (2n + 2) }/ {25 n × 5 (n - 1) }
263 + 1152 - ? + 577 = 1333
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
(72 + 30) ÷ 6 + [{75 ÷ 25) + 6} × 2] = ?
34 × 2.5 + 6.4 × 1.5 – 4.8 × 1.2 =?
